Struct pow_of_2::PowOf2

pub struct PowOf2<T: UInt> { /* fields omitted */ }

Unsigned integer powers of 2.

Internally just an exponent. Consequentially takes advantage of bit-manipulation. Runtime-checked to be valid values of T.

Methods

impl<T: UInt> PowOf2<T>

pub fn try_from_exp(exp: u8) -> Option<Self>

Fails if above Ts domains.

pub fn from_exp(exp: u8) -> Self

Panics if above Ts domains.

pub fn try_pow(self, p: u8) -> Option<Self>

Raise self to a power.

Fails if above T's domain.

pub fn pow(self, p: u8) -> Self

Raise self to a power.

Panics if above T's domain.

pub fn pow_neg(self, p: u8) -> Self

Raise self to a negative power.

Should not panic, simply bottoms out at zero.

pub fn to_uint(self) -> T

Represent as non-exponent.

Should not fail at this point (would fail earlier).

pub fn exp(self) -> u8

Get exponent.
